关于MVC和身份的两个问题 [英] Two questions about MVC, and Identity
问题描述
我很新的身份和MVC，我想创建一个MVC应用程序作为我的第一个项目之一。
我已经能够遵循<一个href=\"http://typecastexception.com/post/2014/06/22/ASPNET-Identity-20-Customizing-Users-and-Roles.aspx\"相对=nofollow>几个教程并已成功添加附加属性我ApplicationUser：IdentityUser类
公共类ApplicationUser
：IdentityUser＆LT;字符串，ApplicationUserLogin，
ApplicationUserRole，ApplicationUserClaim＆GT;
{
[需要]
[显示（名称=用户名）]
[StringLength（50）]
公共字符串句柄{搞定;组; } [StringLength（100的ErrorMessage =您的{0}最多只能{1}个字符长。）]
[显示（名称=名）]
公共字符串名字{获得;组; } [StringLength（100的ErrorMessage =您的{0}最多只能{1}个字符长。）]
[显示（名称=姓氏）]
公共字符串名字{获得;组; } [需要]
[显示（名称=用户创建日期）]
公众的DateTime UserCreationDate {搞定;组; } 公共ApplicationUser（）
{
。this.Id = Guid.NewGuid（）的ToString（）; //添加任何自定义用户属性/ code在这里
}
我的问题是：
-
我看到的电子邮件设置为需要App_Start.IdentityConfig.cs唯一的电子邮件，有没有一种方法来设置它需要像处理一个独特的自定义属性？
VAR经理=新ApplicationUserManager（新UserStore＆LT; ApplicationUser，ApplicationRole，串，ApplicationUserLogin，ApplicationUserRole，ApplicationUserClaim＆GT;（context.Get＆LT; ApplicationDbContext＆GT;（）））;
//配置用户名验证逻辑
manager.UserValidator =新UserValidator＆LT; ApplicationUser＆GT;（经理）
{
AllowOnlyAlphanumericUserNames =假，
RequireUniqueEmail =真
}; -
在Views.Shared._LoginPartial.cshtml的局部视图它显示登录到使用User.Identity.GetUserName（申请的人的用户名/电子邮件）是有参考我的自定义属性的一个途径而是有诸如名字，或办理？
@using Microsoft.AspNet.Identity@if（Request.IsAuthenticated）
{
使用（Html.BeginForm（注销，帐户，FormMethod.Post，新{ID =logoutForm，@class =Navbar的权利}））
{
@ Html.AntiForgeryToken（） ＆LT; UL类=NAV导航栏，导航栏导航右＆GT;
＆LT;立GT;
@ Html.ActionLink（你好+ User.Identity.GetUserName（）+索引，管理，routeValues！：空，htmlAttributes：新{标题=管理}）
＆LT; /李＆GT;
＆LT;立GT;＆LT; A HREF =JavaScript的：的document.getElementById（'logoutForm'）提交（）＆GT;注销＆LT; / A＆GT;＆LT; /李＆GT;
＆LT; / UL＆GT;
}
}
其他
{
＆LT; UL类=NAV导航栏，导航栏导航右＆GT;
＆LT;立GT; @ Html.ActionLink（注册，注册，帐户，routeValues：空，htmlAttributes：新{ID =registerLink}）LT; /李＆GT;
＆LT;立GT; @ Html.ActionLink（登录，登录，帐户，routeValues：空，htmlAttributes：新{ID =LOGINLINK}）LT; /李＆GT;
＆LT; / UL＆GT;
}
实现自定义 UserValidator 已经在这里涵盖：<一href=\"http://stackoverflow.com/questions/27655578/how-can-customize-asp-net-identity-2-username-already-taken-validation-message\">How可以自定义Asp.net身份2名已被使用验证消息？
而不是命中为每个页面请求显示处理数据库，登入过程中添加的索赔。
定义你自己的要求：
公共静态类CustomClaimTypes
{
公共常量字符串句柄=http://schemas.xmlsoap.org/ws/2014/03/mystuff/claims/handle;
}
在登入，设置声明：
专用异步任务SignInAsync（ApplicationUser用户，布尔isPersistent，字符串密码= NULL）
{
AuthenticationManager.SignOut（DefaultAuthenticationTypes.ExternalCookie）; VAR身份=等待UserManager.CreateIdentityAsync（用户，DefaultAuthenticationTypes.ApplicationCookie）; //获取手柄，并添加自称的身份。
VAR手柄= GetTheHandle（）;
identity.AddClaim（新索赔（CustomClaimTypes.Handle，手柄）; AuthenticationManager.SignIn（新AuthenticationProperties（）{IsPersistent = isPersistent}，身份）;
}
然后，通过一个扩展方法，你可以读取它的出路一样 GetUserName（）：
公共静态类IdentityExtensions
{
公共静态字符串GetHandle（此的IIdentity身份）
{
如果（身份== NULL）
返回null; 返回（身份ClaimsIdentity）.FirstOrNull（CustomClaimTypes.Handle）;
} 内部静态字符串FirstOrNull（这ClaimsIdentity身份，串claimType）
{
VAR VAL = identity.FindFirst（claimType）; 返回VAL == NULL？空：val.Value;
}
}
最后，在你看来：
@ User.Identity.GetHandle（）
I am very new to identity and MVC, I am trying to create an MVC app as one of my first projects.
I have been able to follow a few tutorials and have successfully added additional properties to my ApplicationUser : IdentityUser class
public class ApplicationUser
: IdentityUser<string, ApplicationUserLogin,
ApplicationUserRole, ApplicationUserClaim>
{
[Required]
[Display(Name = "UserName")]
[StringLength(50)]
public string Handle { get; set; }
[StringLength(100, ErrorMessage = "Your {0} can be at most {1} characters long.")]
[Display(Name = "First Name")]
public string FirstName { get; set; }
[StringLength(100, ErrorMessage = "Your {0} can be at most {1} characters long.")]
[Display(Name = "Last Name")]
public string LastName { get; set; }
[Required]
[Display(Name = "User Creation Date")]
public DateTime UserCreationDate { get; set; }
public ApplicationUser()
{
this.Id = Guid.NewGuid().ToString();
// Add any custom User properties/code here
}
My questions are:
I see where Email is set to require a unique Email in App_Start.IdentityConfig.cs, Is there a way to set it up to require a unique custom property like Handle?
var manager = new ApplicationUserManager(new UserStore<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>(context.Get<ApplicationDbContext>())); // Configure validation logic for usernames manager.UserValidator = new UserValidator<ApplicationUser>(manager) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true };In the Partial View of Views.Shared._LoginPartial.cshtml it shows the UserName/Email of the person logging into the application using User.Identity.GetUserName() is there a way to reference one of my custom properties there instead such as FirstName, or Handle?
@using Microsoft.AspNet.Identity @if (Request.IsAuthenticated) { using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" })) { @Html.AntiForgeryToken() <ul class="nav navbar-nav navbar-right"> <li> @Html.ActionLink("Hello " + User.Identity.GetUserName() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" }) </li> <li><a href="javascript:document.getElementById('logoutForm').submit()">Log off</a></li> </ul> } } else { <ul class="nav navbar-nav navbar-right"> <li>@Html.ActionLink("Register", "Register", "Account", routeValues: null, htmlAttributes: new { id = "registerLink" })</li> <li>@Html.ActionLink("Log in", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li> </ul> }
Implementing a custom UserValidator has already been covered here: How can customize Asp.net Identity 2 username already taken validation message?
Rather than hitting the database for every page request to display the handle, add a claim during signin.
Define your own claim:
public static class CustomClaimTypes
{
public const string Handle = "http://schemas.xmlsoap.org/ws/2014/03/mystuff/claims/handle";
}
During signin, set the claim:
private async Task SignInAsync(ApplicationUser user, bool isPersistent, string password = null)
{
AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);
var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
//Get the handle and add the claim to the identity.
var handle = GetTheHandle();
identity.AddClaim(new Claim(CustomClaimTypes.Handle, handle);
AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);
}
Then, via an extension method you can read it out the same way as GetUserName():
public static class IdentityExtensions
{
public static string GetHandle(this IIdentity identity)
{
if (identity == null)
return null;
return (identity as ClaimsIdentity).FirstOrNull(CustomClaimTypes.Handle);
}
internal static string FirstOrNull(this ClaimsIdentity identity, string claimType)
{
var val = identity.FindFirst(claimType);
return val == null ? null : val.Value;
}
}
Finally, in your view:
@User.Identity.GetHandle()
